The lymphatic system helps to transport lymph, a fluid containing immune cells, throughout the body to fight infections. How do B cells contribute to the immune response? B cells produce antibodies that bind to specific antigens, marking them for destruction by other immune cells. What are the primary components of the innate immune system? The primary components of the innate immune system include physical barriers (like skin), phagocytic cells, and antimicrobial proteins. How do the complement proteins assist in the immune response? Complement proteins enhance the ability of antibodies and phagocytic cells to clear pathogens and damaged cells. 2 What is the role of helper T cells in the immune response? Helper T cells coordinate the immune response by activating other immune cells, including B cells and cytotoxic T cells. What is the significance of memory cells in the immune system? Memory cells remember previously encountered pathogens and enable a faster and stronger response upon subsequent exposures. How does the body develop immunological tolerance? Immunological tolerance is developed when the immune system learns to recognize and not attack the body’s own tissues. What are the main differences between a primary and secondary immune response? The primary immune response occurs upon first exposure to a pathogen and is slower, while the secondary immune response is faster and more robust due to memory cells. How do interferons function in the immune system? Interferons are signaling proteins released by infected cells that help other cells resist viral infection. 3 What is the role of the spleen in the immune system? The spleen filters blood, removes old or damaged blood cells, and helps to detect and respond to pathogens in the bloodstream. What is the primary function of the immune system? The primary function of the immune system
